| 中文摘要: |
| 针对辽宁省中西部地区春旱频繁、土壤风蚀严重的特点,设置1∶2轮耕、1∶1轮耕、铁茬垄侧播种、铁茬茬间播种、铁茬茬间播种覆盖、保墒蓄水耕作及灭茬后原垄播种(对照)等不同耕作措施,研究其玉米生长发育的差异状况。结果表明:保护性耕作措施有利于玉米4叶期后植株的生长发育,铁茬茬间播种覆盖和铁茬茬间播种处理的效果明显优于其它耕作措施。 |
| 英文摘要: |
| In the medial and western areas of Liaoning province spring droughts occured frequently,and soil wind erosion is seriously.According to the characters,6 tillage managements such as 1∶2 rotation,1∶1 rotation,stubble and sowing in ridge side,ridge sowing between stubbles,ridge sowing between stubbles and multh,collecting water and moisture-retaining tillage,ridge sowing after stubble breaking(CK) were designed to study the effects of different tillage managements on growth and development of maize.The results showed that the conservation tillage managements are advantageous to the growth and development of maize after 4 leaves stage.The ridge sowing between stubbles,ridge sowing between stubbles and multh are obviously superior to other tillage managements. |
